Abstract
A correlation demodulator unit () having gain normalization includes a correlation demodulator () for receiving a signal from a receiver (). The correlation demodulator has a plurality of correlators (C-C) corresponding to a plurality of N correlator outputs. A gain normalizer () is coupled to the correlation demodulator for accumulating symbol energy on a symbol by symbol basis for each of the plurality of correlator outputs based upon a current symbol decision providing at least an accumulated value within an accumulator () for the plurality of correlators and for normalizing the plurality of N correlator outputs using the accumulated value(s).
